unavail rpool SSD

[Robkd4]

Hi all,

have a fresh installed pve on a SSD Mirror pool, but degraded. How can i remove the missing drive and re add?

# zpool status -x
  pool: rpool
 state: DEGRADED
status: One or more devices could not be used because the label is missing or
        invalid.  Sufficient replicas exist for the pool to continue
        functioning in a degraded state.
action: Replace the device using 'zpool replace'.
   see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-4J
config:

Best way is to have a spare slot disk usable on your host.
If present, you cannot use "zpool replace"
But, the safely use of them is with zpool offline mode.

The Proxmox manual has a section named Changing a failed bootable device: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysadmin_zfs_change_failed_dev

On a boot zfs mirror (/raidz*) a "zpool replace" (iO for option pools) alone and even a spare disk alone would NOT do the full job (works only for part3), see link by leesteken !!

thx a lot for all your answers,

but just rebuild from scratch. cleaned all the drives with wipefs created new pools and now all looks fine.

cheers
